Did you know most animals eat penguins, chicks, and their eggs? Penguins live in Antarctica. Penguins eat krill, fish, squid, crustaceans, and Amphipods. Penguins live up to 15 to 20 years. A female penguin lives up to 17 years. In general, penguins that live closer to the equator eat more fish and penguins closer to Antarctica eat more squid & krill. The penguin species with the highest population is the Macoroni penguin with 11,654,000 pairs. The species between 6,000-15,000 individuals. There are 17 species of penguins, each slightly different. While other birds have wings for flying, penguins have adapted flippers to help them swim in the water. The reason why I researched on penguins is because they are excellent swimmers.
